叶面积指数估算中，关于孔隙率计算的代码，考虑了不同的树冠形状（椭圆形、圆锥形、圆锥+椭圆形），并且可基于孔隙率估算叶面积指数和聚集指数。代码包含了连续植被（比尔定律）、和离散植被的情况，离散植被中假设树干在空间上满足随机分布。使用时请引用文献：尹高飞, 柳钦火, 李静,  曾也鲁, 徐保东. 树冠形状对孔隙率及叶面积指数估算的影响分析. 遥感学报, 2014, 18(4), 752 – 759.

刚才弄错了，这才是第二个源码，可以实现输入一二叉树的前序与中序，输出其后序-have just made a mistake, this is the second source, can achieve an input sequence of binary tree with the sequence, then the output sequence

用abaqus有限元软件建立复合材料模型，利用fortran语言编写复合材料三维渐进损伤子程序。程序中自己定义复合材料本构模型，损伤准则采用三维hashin判据。

This program is to handle all possible arithmetic operations (+, -, *, /, %) and logic operations (, >=, =,

Joseph环问题描述如下：编号是2，n个人按照顺时针方向围坐一圈，每个人只有一个密码（正整数）。一开始任选一个正整数作为报数上限值1开始顺序报数，报到m的人出列，将他的密码作为新的1报数，如此下去，直到所有人全部出列为止。设计一个程序来求出出列顺序。

资源描述This paper presents a lowcost indoor location identification and material tracking methodology for construction projects using Ultra High Frequency (UHF) passive Radio Frequency Identification (RFID) technology. Onsite location aware information is an emerging area that focuses on automating delivery of spatial information pertinent to location of materials, workforce, and equipment. This spatial information can be used to derive knowledge about construction project status. A two-step algorithm is presented to automate the process of location estimation and material tracking in near-real-time. In this methodology, a number of passive RFID tags are distributed onsite where work is progressing, and a mobile RFID reader is carried by a worker onsite. Each passive RFID tag is deployed as a reference point with a known location (landmark) within a predefined zone. Reference tags of known locations are used to d

这是经典的一种电阻率三维反演的代码，在地球物理勘探领域有着非常广泛的应用，具有重要的研究和应用价值，本程序只与大家开展交流，请不要商业化。。。
